Pentax Auto 110 Mysterious Light Leak

[tzeH]

Hi,

on most of my pictures I get a light leak that looks like it's sprayed on from the left side. Intensity, size and number of dots varies on each photo and sometimes it's not there but it's always on the left.
Also, I had this on different films. All by lomography though, as they are the only suppliers that still sell 110 film (afaik).

The only similar thing I can find on the web is the first one here but the A110 has no shutter cloth by design...

Does anybody have an idea what that might be? I can't find a way to reproduce it without film in it (I put tracing paper where the film should be)!

Cheers!

Edit: It's holes in the backing paper! (See here)

It looks like defects in expired film to me.

Thanks for the idea! Maybe. Added a few infos on top to clarify.

I had identical issues on several rolls, which I didn't buy at the same time... So I think it's unlikely but not impossible.

It is mysterious, you should give us more information. Like does the leak extend to the edge of the photo or over, does the leak go into the area of the undeveloped portion of the film, I think the 110 has changeable lenses: did you use other lenses? It would be helpful if you posted a scan for the entire negative including both sides of the frame and all of the unexposed area.

It's a light leak through the backing paper. The shape is the shape of the number viewing window. I would try light-excluding tape (or black duct tape if you have nothing else), run a cartridge through with outdoor light exposure and see if that fixes the issue.

It might actually be a Lomography issue but I suspect that other users might do differently with their cameras so not have such obvious problems.

Ha! Spot on! Searching for that, I found this link which explains exactly that. Thank you!
I guess I'll just cover the number window...
